Ah got ya lol, well every time I go to the shop where I get my oil and filter they say I'm getting the wrong oil when I pick up 5w 40, and say I should be using 5w-30. I've already told em it's the import version at this point, and so I reply can you show me what exhaust manifold to turbo gasket I need also please....which returns a severly confused look on his arrogant face...after he's typed on his keyboard and realised "computer says no" It just shows a lot of these shops only know what their little Database tells them and don't understand using an oil slightly thinner than that can be a benefit on these engines, like I say mate I use 5w-40 fully synth, a lot of people on here and tgtt including opie oils recommend it....the shop I go to say 5w 30 as I assume that's what a uk starlet uses from factory, I'm sure under my bonnet it says 10w 30 also but I think that's a more jap grade oil that you'll struggle to Find over here.
